Solution
| Marks Obtained | No. of students (c.f.) |
| less than 10 | 8 |
| less than 20 | 25 |
| less than 30 | 38 |
| less than 40 | 50 |
| less than 50 | 67 |
Steps of construction:
- Plot the points (10, 8), (20, 25), (30, 38), (40, 50) and (50, 67) on the graph.
- Join them with free hand to obtain an ogive.
